The primary aim in treating esophageal varices is to prevent bleeding. Bleeding esophageal varices are life-threatening. If bleeding occurs, treatments are available to try to stop the bleeding.
Treatment to prevent bleeding
Treatments to lower blood pressure in the portal vein may reduce the risk of bleeding esophageal varices. Treatments may include:
- Medications to reduce pressure in the portal vein. A type of blood pressure drug called a beta blocker may help reduce blood pressure in your portal vein, decreasing the likelihood of bleeding. These medications include propranolol (Inderal, Innopran) and nadolol (Corgard).
Using elastic bands to tie off bleeding veins. If your esophageal varices appear to have a high risk of bleeding, your doctor might recommend a procedure called band ligation.
Using an endoscope, the doctor snares the varices and wraps them with an elastic band, which essentially "strangles" the veins so they can't bleed. Esophageal band ligation carries a small risk of complications, such as scarring of the esophagus.
Treatment if you're bleeding
Bleeding varices are life-threatening, and immediate treatment is essential. Treatments used to stop bleeding and reverse the effects of blood loss include:
- Using elastic bands to tie off bleeding veins.
- Medications to slow blood flow into the portal vein. A drug called octreotide (Sandostatin) is often used with endoscopic therapy to slow the flow of blood from internal organs to the portal vein. The drug is usually continued for five days after a bleeding episode.
Diverting blood flow away from the portal vein. Your doctor might recommend a procedure called transjugular intrahepatic portosystemic shunt (TIPS) to place a shunt. The shunt is a small tube that is placed between the portal vein and the hepatic vein, which carries blood from your liver to your heart. The shunt reduces pressure in the portal vein and often stops bleeding from esophageal varices.
But TIPS can cause serious complications, including liver failure and mental confusion, which can develop when toxins that the liver normally would filter are passed through the shunt directly into the bloodstream. TIPS is mainly used when all other treatments have failed or as a temporary measure in people awaiting a liver transplant.
- Restoring blood volume. You might be given a transfusion to replace lost blood and clotting factor to stop bleeding.
- Preventing infection. There is an increased risk of infection with bleeding, so you'll likely be given an antibiotic to prevent infection.
- Replacing the diseased liver with a healthy one. Liver transplant is an option for people with severe liver disease or those who experience recurrent bleeding of esophageal varices. Although liver transplantation is often successful, the number of people awaiting transplants far outnumbers the available organs.
Bleeding will recur in most people who have bleeding from esophageal varices. Beta blockers and esophageal band ligation are the recommended treatments to help prevent rebleeding.
